(H. XIV fig. 4a) of a diameter of about 1 mm ; the longer sper- 



matocysta forming a long cul-de-sac (fig. 46). The mucous glatid 



whitish, in the neighborhood of the anterior end was a yolk-yellow 



part. 



2. Chromodoris Californiensis, Bergh, n. sp. PI XII. fig. 5 to 15. 



Color caeruleseens, dorso et lateribus punctus fnajoribus aureis 

 ornatus. 



Hab. Oc. Pacific, septentr. (coast of California, Santa Barbara 

 Islands). 



Of this very 'handsome species Uall obtained an individual on 

 alga? at low water in the harbor of Catalina Island, California, 

 January, 1874. (Specimens have also been seen from Monterey 

 and San Diego. W. H. D.) 



The color of the living animal, according to Dall, was " ma- 

 zarin-blue with golden spots" (changing to greenish-blue in the 

 alcohol, which it continues to color for a long time, and after 

 several changes for fresh spirit. W. H. P.). 



The rather contracted animal in spirits was 12.0 mm. long, and 

 6.0 mm. broad and high. The height of the retracted rhinophoria 

 was 1.3 mm., of the retracted branchial plumes 1.5 mm., the length 

 of the tail about 2.5 mm., and the breadth of the foot 2.0 mm. 



The color was uniformly greenish-blue (which it had also given 

 out to the alcohol). On the back were several yellowish-white, 

 round spots, a millimetre in diameter. On the anterior part they 

 were chiefly in the median line, on the rest in two longitudinal 

 series, outside of which on the back were scattered some similar 

 spots and on each side of the body was a line of four or five more 

 of the same kind. A brighter, fine line seemed to border the 

 margin of the mantle-edge and that of the foot. The rhinophoria 

 were green-blue, the gills dark green-blue ; the internal connecting 

 branchial " mesenterium " and the root of the branchial leaves 

 partly silver-white. 



The form as usual. The mantle-edge little prominent except 

 over the head and tail, the breadth on this last part being about 

 1.65 mm.; on the under side of the caudal veil thus formed were 

 six' semi-globular nodules (fig. 5) one full mm. in diameter. The 

 tentacles as usual; the club of the rhinophoria with about twenty 

 leaves. The gills formed of nine leaves of nearly equal size; the 

 anal papilla rather low; posteriorly completing the branchial ring. 

 The peritoneum with a light-bluish hue. The pericardium bluish.
